originating from the unknown prefix "sha-" and the onomatopoeic "bonk", suggesting a striking motion.

A silly word that doesn't have any particular meaning, other than to express a lack of insight to offer regarding a particular topic of discussion. Can also be used as an expletive, to express confusion, disgust, excitement...but the beauty of the word is not only its versatility in meaning, but the fact that it is disarming gibberish to be uttered when tension needs to be broken.
